ETI ETIMAT P10 Circuit Breaker 3P 20A B 10kA (1901311)

ETIMAT P10 by ETI is a three-pole circuit breaker designed to protect AC electrical circuits against overload and short circuit. It is used in distribution boards of residential, administrative, and small commercial installations, especially where a three-phase line or a group of consumers must be disconnected simultaneously. The 3P design allows all phases of the circuit to be switched off at the same time, which is important for coordinated protection of the line. The device is rated at 20 A, so it is suitable for circuits with moderate load. Tripping characteristic B makes it appropriate for lines with mainly resistive loads and low inrush current, as it responds quickly to short-circuit currents with only limited start-up surges. This characteristic is commonly chosen for lighting circuits and other standard distribution lines where fast disconnection is required in the event of a fault. The breaking capacity is 10 kA, which means the breaker can interrupt high fault currents in networks with elevated short-circuit levels. This parameter is important for maintaining the safety of both the electrical installation and the connected equipment. The breaker is designed for AC voltage and operates at a rated voltage of 415 V AC with a frequency of 50/60 Hz, making it compatible with standard power systems used in modern electrical networks. Another important parameter is the rated impulse withstand voltage Uimp of 6 kV, which indicates resistance to short-term overvoltage events in the network. The permissible conductor cross-section is 1 to 25 mm², so the breaker can be connected to commonly used cable and wire sizes in power and distribution circuits. The product complies with EN/IEC 60898, the standard for modular circuit breakers intended for household and similar installations. With its 3-pole configuration, 20 A rating, B tripping curve, and 10 kA breaking capacity, this circuit breaker is a practical solution for protecting supply lines in electrical distribution systems where reliable line isolation and fault protection are required.
